Compared with the prior art, the frequency of the sound wave is 12K that the human body can perceive and accept. The massage projection effect of the sound wave can improve the relaxation of the eye ciliary muscle, and also has penetrability, slow down the lengthening of the eye axis, promote the exchange of metabolic substances, strengthen the local blood circulation, and improve the recovery of eye fatigue. When the sound wave is projected on the medium, the medium particle moves back and forth in its equilibrium position, which causes rhythmic frequency change in the medium. This frequency change forms the pressure change. Under the action of this fast changing pressure, the ciliary muscle and crystal of the eye have tiny changes, making them return to their original state.
